Control of AAD-1 monocot volunteers in fields of dicot crops

ABSTRACT

The subject invention relates in part to the control of AAD-1 monocot volunteers in fields planted with dicot crops such as soybeans or cotton. According to some embodiments of the subject invention, cyclohexanedione herbicides are selected as being an effective tool for controlling AAD-1 volunteers, as AAD genes do not impart tolerance to this class of graminicide chemistry. In addition, imidazolinone-class herbicides can be used in some preferred embodiments for selective control of conventional or herbicide-tolerant varieties of volunteer corn. AAD-1 corn comprising Event DAS-40278-9 is used in some particularly preferred embodiments.

CROSS REFERENCE TO RELATED APPLICATIONS

This application is a 371 national stage application of International Application No. PCT/US2010/045870, with an International Filing Date of Aug. 18, 2010, which claims priority to U.S. Application No. 61/235,248, filed on Aug. 19,2009, and to U.S. Application No. 61/328,944, filed on Aug. 28, 2010, all of which are incorporated herein by reference in their entirety.

BACKGROUND

Corn (monocot) and soybeans (dicot), for example, can be rotated in various crop rotation cycles in various geographies. Cotton is also a dicot.

“Volunteer” plants are unwanted plants from the prior growing season that emerge in a field planted with crops for the current growing season. Volunteers are basically weeds, and can, like weeds, reduce harvest and yield of the crop of interest for the current growing season. The volunteers divert fertilizer resources and the like from the desired crops.

Unlike plain weeds, volunteers are often specifically engineered to be resistant to some herbicides. Thus, controlling volunteers can be more difficult than controlling naturally occurring weeds.

AAD (aryloxy alkanoate dioxygenase) genes as described herein impart high levels of tolerance to 2,4-D herbicides in plants that are transformed with an AAD gene.

AAD-1 genes (encoding SEQ ID NO:1, SEQ ID NO:2, and SEQ ID NO:3, for example, of the attached sequence listing; see WO 2005 107437) also impart high levels of tolerance to phenoxy- and aryloxyphenoxyproplonate herbicides (“fops” such as fluazifop and haloxyfop) to corn and other monocot species transformed with the gene. (Fops are primarily used to control monocots, as dicots tend to have some natural resistance to fops.) Thus, AAD-1 allows the use of some fops as either selection agents or as herbicides on crops where crop destruction would be expected without the AAD-1 gene.

AAD-12 and AAD-13 genes also impart high levels of tolerance to pyridyloxyacetate herbicides (such as triclopyr and fluroxypyr; “pyrs”). Thus, AAD-12 and AAD-13 each allow the use of pyrs as either selection agents or as herbicides on crops where crop destruction would be expected without the AAD-12 or AAD-13 gene.

There are very numerous types of monocot- or grass-only herbicides (that kill monocots).

ACCase inhibitor herbicides include fops and dims.

BRIEF SUMMARY

The subject invention relates in part to the control of AAD-1 monocot volunteers in fields planted with dicot crops such as soybeans or cotton.

The subject invention also relates in part to the recognition that one potential downside to the use of AAD genes is that volunteers can be resistant to 2,4-D, as well as to fops (in the case of AAD-1). In the case of AAD-1, fop herbicides will no longer be effective for control of volunteer AAD-1 corn in fields planted with dicot crops such as soybean or cotton. The subject invention relates in part to the recognition that when an AAD gene is stacked with other herbicide resistance traits (such as glyphosate, glufosinate, and the like) in corn, control of volunteer corn plants in the following year can be an issue.

According to some embodiments of the subject invention, cyclohexanedione (‘dim’) herbicides (such as clethodim, sethoxydim, and the like) are selected, from almost innumerable other options, as being an effective tool for controlling AAD-1 ‘volunteers,’ as AAD genes do not impart tolerance to this class of graminicide chemistry. Dims tend to be moncot-specific.

In addition, the following imidazolinone-class herbicides can be used, in some preferred embodiments, according to the subject invention: imazethapyr, imazamox, and imazaquin. Soy is naturally tolerant to these herbicides, so these imidazolinones can be used for selective control of conventional or herbicide-tolerant varieties of volunteer corn. (Non-commercialized CLEARFIELD cotton and imidazolinone-resistant soy was developed by BASF; cotton is not naturally tolerant to imidazolinones.)

This is assuming that the corn from the previous season was susceptible to imidazolinones. (Soybeans are naturally tolerant to certain imidazolinones.) Corn is generally susceptible to imidazolinones except for CLEARFIELD corn, which is tolerant to imidazolinones.

Use of other types of herbicides, including ALS—(acetolactate synthase) and/or AHAS—(acetohyroxyacid synthase) inhibitors could also be used according to the subject invention for the control of volunteer AAD monocot plants as well.

A third option, according to the subject invention, is to use other herbicides, as described herein, for controlling AAD-1 volunteers. These options include herbicides that provide a relatively fast “burn down,” and non-selective herbicides, such as paraquat, used pre-plant.

AAD-1 corn comprising Event DAS-40278-9 is used in some particularly preferred embodiments.

BRIEF DESCRIPTION OF THE SEQUENCES

SEQ ID NO:1 is the native protein sequence encoded by the AAD-1 v1 gene from Sphingobium herbicidivorans.

SEQ ID NO:2 is the amino acid sequence encoded by the AAD-1 v2 gene, which removed an internal NotI restriction site.

SEQ ID NO:3 is the amino acid sequence encoded by the AAD-1 v3 gene, which has plant codon usage for expression in a plant.

SEQ ID NO:4 is a sequence for corn Event DAS-40278-9, which includes 5′ and 3′ corn genomic flanking sequences, and the AAD-1 cassette insert sequence.

DETAILED DESCRIPTION

As used herein and unless otherwise specified, preferred dicots are soybeans or cotton.

ACCase inhibitor herbicides include fops and dims.

One aspect of the subject invention includes the use of ‘dim’ herbicides to remove volunteer AAD-1 corn in fields of dicots. In some specific embodiments, the AAD-1 gene is present in the corn as the AAD-1 corn event designated DAS-40278-9 having seed deposited with American Type Culture Collection (ATCC) with Accession No. PTA-10244 (Yellow Dent maize hybrid seed (Zea Mays L.):DAS-40278-9; Deposited in accordance with the Budapest Treaty on behalf of Dow AgroSciences LLC; Date of receipt of seeds/strain(s) by the ATTC: Jul. 10, 2009; viability confirmed Aug. 17, 2009), and progeny derived thereof. See also SEQ ID NO:4. This event is disclosed in U.S. Ser. No. 61/235,248 (filed Aug. 19, 2009). Such AAD-1 monocot volunteers could be present in the following year's soybeans, cotton, or other broadleaf crop. Thus, the subject invention includes the application of a dim (or other as disclosed herein) herbicide to volunteer AAD-1 corn plants, particularly where the corn plant comprises the 40278-9 event.

Because of the specific detoxifying aspects of AAD genes, ‘dim’ herbicides would not be subject to detoxification by AAD-1, and AAD-1 monocot volunteers would remain highly susceptible to dim herbicides. Thus, the subject invention includes the use of one or more dim herbicides, where the AAD-1 gene was used alone or stacked with other herbicide tolerance traits.

In some other preferred embodiments, imidazolinones can be used according to the subject invention to control monocot/corn volunteers in dicot fields. If the corn was susceptible to an imidazolinone and the dicots are resistant to imidazolinones, then a “dim” and/or imidazolinone herbicide could be used in the dicot fields to control the AAD-1 corn volunteers. However, if CLEARFIELD corn (which is resistant to imidazolinones), for example, was planted in the previous season, this would tend to preclude the use of imidazolinones the following season to control corn volunteers in dicot fields.

As alluded to above, selection of herbicides to use on the current planted fields, according to the subject invention, depends in part on the herbicide-tolerant trait(s) that are present in both the volunteers (the monocot crop of the prior season), if any, and the herbicide resistance trait(s) that are present in the field of dicot crops of the current growing season. Thus, additional herbicide chemistries can be selected to provide control of AAD-1 corn depending on the stack, if any, with other herbicide tolerant traits in the corn, and on the tolerance or susceptibility of the dicot (soybeans or cotton) in the field to be treated.

For example, if the volunteer AAD-1 corn was also stacked with a glyphosate- or glufosinate-trait, then glufosinate or glyphosate, respectively, could be used in the soybean field of the current season, assuming that the soybeans also have a resistance trait against glufosinate or glyphosate, respectively.

If the volunteer AAD-1 corn was also stacked with a glyphosate- and glufosinate-traits, then dims and/or imidazolinones could still be used in the soybean fields to control the AAD-1 corn volunteers (again assuming that the corn does not have a resistance trait against an imidazolinone if an imidazolinone is used to control the volunteers).

When an AAD-1 gene was used alone in corn in the previous growing season, imidazolinone, “dims,” glyphosate, and/or glufosinate could be used the following season to control the volunteer AAD-1 corn in planted fields of soybean or cotton that, assuming that the dicots are tolerant/resistant to any one or more of these further herbicides (such as glyphosate and/or glufosinate). That is, glyphosate and/or glufosinate could be used if the soybeans or cotton are engineered or bred to be tolerant to glyphosate and/or glufosinate, respectively.

When an AAD-1 gene was stacked in corn with, for example, a glyphosate or glufosinate resistant trait (such as is found in Roundup Ready [or GAT or other glyphosate-tolerant crops] or Liberty Link [or other glufosinate-tolerant] corn), then imidazolinone and/or a “dim” herbicide could be used to control volunteer AAD-1 corn in the dicot crops (assuming the dicot crop is resistant to imidazolinone if an imidazolinone herbicide is to be used).

Glufosinate or glyphosate, respectively, could also be used, assuming that the dicot crops are resistant to that herbicide and the corn is susceptible. That is, if the soybeans have a trait for glyphosate tolerance but not glufosinate tolerance, for example, then glyphosate could also be used (assuming ROUNDUP READY corn is not the volunteers). If the soybeans have a glufosinate tolerance trait (such as PAT) but not a glyphosate tolerance trait, then glufosinate could also be used (assuming that LIBERTY LINK corn is not the volunteers).

In any of those stacking scenarios (and even if AAD-1, glyphosate tolerance, and glufosinate tolerance, and imidazolinone tolerance traits were all present in the corn of the previous season), dims could be used in the soybean fields to control the AAD-1 corn volunteers.

In some embodiments, AAD-1 monocot volunteers can be controlled, using combinations of herbicides disclosed herein—see Examples 4 and 5, in fields of monocots. These embodiments include control of AAD-1 Event DAS-40278-9 corn volunteers in fields of monocots. Such embodiments include turf-in-turf (AAD-1 turf volunteers in a field of other (non-AAD1) turf.

EXAMPLES Example 1 Control of Volunteer AAD Maize in a Field Planted with Soybean Using Alternative Herbicides

In one embodiment, volunteer transgenic maize lines containing an AAD expression cassette (AAD-1) are controlled within a field of soybean by the application of a herbicide or combination of herbicides. The specific herbicide used to control the volunteer transgenic AAD maize line is dependent upon the type of soybean seed being planted within the field (e.g., conventional soybean, Round-up Ready Soybean, Liberty Link Soybean, etc.).

Furthermore, the AAD trait may be stacked with other additional herbicide tolerant trait(s) via conventional breeding or a molecular stack. In such an example, the specific herbicide used to control the volunteer AAD maize stacked with another herbicide tolerant trait(s) will be dependent upon the additional herbicide tolerant trait(s) and the type of soybean being planted within the field.

The application of a given herbicide can be made before planting at pre-emergence/burndown or post-emergence after planting to control the volunteer transgenic AAD maize lines. Table 1 lists the herbicides to be used at the different stages of planting (pre-emergence or post-emergence) to control volunteer transgenic AAD maize. At or about a 1× Field Rate concentration of herbicide would be applied, as either a tank mix or alone, to the field for both pre-emergent and post-emergent volunteer control.

The control of transgenic maize plants containing the AAD expression cassette within a field of soybean would be applicable for the control of volunteer AAD transgenic monocot plants (including, but not limited too; corn, rice, sugar cane, switch grass, turf grass species, sorghum, barley, wheat, and oats, and durum) within a field being planted with a dicot crop (including, but not limited too; soybean, cotton, canola, flax, sunflower, legumes, alfalfa, peanut, and tomato). The example described above, in which volunteer transgenic AAD maize plants are controlled in a soybean field, is illustrative of the invention and not intended to restrict the scope of this embodiment.

Example 2 Control of Volunteer Corn (Conventional or Containing Non-AAD Herbicide Tolerance Traits) in a Field Planted with AAD Soybean Using Alternative Herbicides

In an embodiment, volunteer transgenic corn lines (containing the Clear Field trait, Roundup Ready or other Glyphosate Tolerant Trait, Liberty Link Trait, Imidazolonine tolerant trait, or any stacked combination thereof) or volunteer conventional corn lines are controlled within a field of transgenic AAD soybean (AAD-12) by the application of a herbicide or combination of herbicides. The specific herbicide used to control the volunteer corn plants is dependent upon the type of corn seed being planted within the field (e.g., conventional soybean, Round-up Ready Soybean, Liberty Link Soybean, etc.). Additionally, the specific herbicide used to control the volunteer conventional or transgenic corn line is dependent upon the type of AAD transgenic soybean seed (i.e. stacked traits or alone) being planted within the field and the trait possessed by the volunteer corn line.

The application of a given herbicide can be made before planting at pre-emergence/burndown or post-emergence after planting to control the volunteer conventional or transgenic soybean lines. Table 2 and Table 3 list the herbicides to be used at the different stages of planting (pre-emergence or post-emergence) to control volunteer conventional or transgenic corn. At or about a 1× Field Rate concentration of herbicide would be applied, as either a tank mix or alone, to the field for both pre-emergent and post-emergent volunteer control.

The control of conventional or transgenic corn plants containing a herbicide tolerant expression cassette within a field of AAD transgenic soybean (either stacked with other herbicide tolerant traits or alone) would be applicable for the control of a conventional or herbicide tolerant transgenic monocot plant (including, but not limited too; corn, rice, sugar cane, switch grass, turf grass species, sorghum, barley, wheat, and oats, and durum) within a field being planted with an AAD transgenic dicot crop (including, but not limited too; soybean, cotton, canola, flax, sunflower, legumes, alfalfa, peanut, and tomato). The example described above, in which volunteer conventional or transgenic herbicide tolerant corn plants are controlled in a field planted with AAD transgenic soybean, is illustrative of the invention and not intended to restrict the scope of this embodiment.

Example 3 Control of Volunteer AAD-1 Maize in a Field Planted with AAD-12 Cotton Using Alternative Herbicides

In one embodiment, volunteer transgenic maize lines containing an AAD-1 expression cassette are controlled within a field of AAD-12 cotton by the application of a herbicide or combination of herbicides. The specific herbicide used to control the volunteer transgenic AAD-1 maize line is dependent upon the type of AAD-12 cotton seed being planted within the field (e.g., AAD-12 cotton or AAD-12 cotton stacked with Round-up Ready, Liberty Link, or other herbicide tolerant traits).

Furthermore, the AAD-1 trait may be stacked with other additional herbicide tolerant trait(s) via conventional breeding or a molecular stack. In such an example, the specific herbicide used to control the volunteer AAD-1 maize stacked with another herbicide tolerant trait(s) will be dependent upon the additional herbicide tolerant trait(s) and the type of cotton being planted within the field.

The application of a given herbicide can be made before planting at pre-emergence/burndown or post-emergence after planting to control the volunteer transgenic AAD-1 maize lines. Table 4 lists the herbicides to be used at the different stages of planting (pre-emergence or post-emergence) to control volunteer transgenic AAD-1 maize. At or about a 1× Field Rate concentration of herbicide would be applied, as either a tank mix or alone, to the field for both pre-emergent and post-emergent volunteer control.

The control of transgenic maize plants containing the AAD-1 expression cassette within a field of AAD-12 cotton would be applicable for the control of volunteer AAD-1 transgenic monocot plants (including, but not limited too; corn, rice, sugar cane, switch grass, turf grass species, sorghum, barley, wheat, and oats, and durum) within a field being planted with an AAD-12 dicot crop (including, but not limited too; soybean, cotton, canola, flax, sunflower, legumes, alfalfa, peanut, and tomato). The example described above, in which volunteer transgenic AAD-1 maize plants are controlled in an AAD-12 cotton field, is illustrative of the invention and not intended to restrict the scope of this embodiment.

footnotes: GT = any glyphosate specific tolerance trait including Roundup Ready (CP4), TIPS EPSPS (GA21, Glytol, DMMG), Athenix's EPSPS, GAT only without ALS, GOX, glyphosate decarboxylase, etc. ALS = double mutant ALS gene insensitive to all ALS herbicide chemistries including IMI herbicides. AAD-1 = Aryloxyalkanoate dioxygenase gene providing tolerance to all commercial phenoxy auxin and all aryloxyphenoxypropionate (fop) herbicides. AAD-12 = Aryloxyalkanoate dioxygenase gene providing tolerance to phenoxyacetic auxin and pyridyloxyacetic auxin herbicides. PAT = phosphinothricin acetyltransferase gene providing tolerance to glutamine synthetase inhibitors including, but not limited to, glufosinate. Similar phenotype is provided by genes such as BAR, DSM1, DSM2, et al. AHAS = imidazolonine specific tolerance gene associated with point mutation at S623 of ALS gene (maize sequence) or equivalent amino acid in other spp (e.g., S653 in Arabidopsis).

Example 4 Control of Volunteer AAD Maize in a Field Planted with Maize Using Alternative Herbicides

In another embodiment, volunteer transgenic maize lines containing the AAD expression cassette (AAD-1) are controlled within a field of maize by the application of a herbicide or combination of herbicides. The specific herbicide used to control the volunteer transgenic AAD maize line is dependent upon the type of maize seed being planted within the field (e.g., Clear Field Maize, Round-up Ready Maize, Liberty Link Maize, etc.).

Furthermore, the AAD trait may be stacked with other additional herbicide tolerant trait(s) via conventional breeding or a molecular stack. In such an example, the specific herbicide used to control the volunteer AAD maize stacked with another herbicide tolerant trait(s) will be dependent upon the additional herbicide tolerant trait(s) and the type of maize being planted within the field.

The application of a given herbicide can be made before planting at pre-emergence/burndown or post-emergence after planting to control the volunteer transgenic AAD maize lines. Table 5 lists the herbicides to be used at the different stages of planting (pre-emergence or post-emergence) to control volunteer transgenic AAD maize. At or about a 1× Field Rate concentration of herbicide would be applied, as either a tank mix or alone, to the field for both pre-emergent and post-emergent volunteer control.

The control of transgenic maize plants containing the AAD expression cassette within a field of maize would be applicable for the control of an AAD transgenic monocot plant (including, but not limited too; corn, rice, sugar cane, switch grass, turf grass species, sorghum, barley, wheat, and oats, and durum) within a field being planted with a monocot crop (including, but not limited too; corn, rice, sugar cane, switch grass, turf grass species, sorghum, barley, wheat, and oats, and durum). The example described above, in which volunteer transgenic AAD maize plants are controlled in a maize field, is illustrative of the invention and not intended to restrict the scope of this embodiment.

Example 5 Control of Volunteer Maize in a Field Planted with AAD-Maize Using Alternative Herbicides

In an embodiment, volunteer transgenic maize lines (containing the Clear Field trait, Roundup Ready or other Glyphosate Tolerant Trait, Liberty Link Trait, Imidazolonine tolerant trait, or any stacked combination thereof) or volunteer conventional maize lines are controlled within a field of transgenic AAD maize (AAD-1) by the application of aryloxyphenoxypropionate herbicide (Fops) including, but not limited to; quizalofop, haloxyfop, fenoxaprop, fluazifop, et al., their stereospecific isomers or racemic mixtures, and esters, acid, or salts thereof. In addition, the Fops herbicide may be applied with another herbicide(s) to control the volunteer maize lines described above.

The specific herbicide used to control the volunteer conventional or transgenic maize line is dependent upon the type of AAD transgenic maize seed (i.e. stacked traits or alone) being planted within the field and the trait possessed by the volunteer maize line. For example an AAD-1 transgenic maize line that has been stacked with another herbicide tolerant trait such as PAT could be sprayed with a herbicide mixture containing a Fop and glufosinate, but only where the preceding volunteer plants do not contain PAT (or other glufosinate tolerant trait) and AAD-1.

The application of a given herbicide can be made before planting at pre-emergence/burndown or post-emergence after planting to control the volunteer conventional or transgenic maize lines. Table 6 lists the herbicides to be used at the different stages of planting (pre-emergence or post-emergence) to control volunteer conventional or transgenic maize. At or about a 1× Field Rate concentration of herbicide would be applied, as either a tank mix or alone, to the field for both pre-emergent and post-emergent volunteer control.

The control of conventional maize plants or transgenic maize plants containing a herbicide tolerant expression cassette within a field of AAD transgenic maize (either stacked with other herbicide tolerant traits or alone) would be applicable for the control of a herbicide tolerant transgenic monocot plant (including, but not limited too; corn, rice, sugar cane, switch grass, turf grass species, sorghum, barley, wheat, and oats, and durum) within a field being planted with an AAD monocot crop (including, but not limited too; corn, rice, sugar cane, switch grass, turf grass species, sorghum, barley, wheat, and oats, and durum). The example described above, in which volunteer transgenic herbicide tolerant maize plants are controlled in a field planted with AAD transgenic maize, is illustrative of the invention and not intended to restrict the scope of this embodiment.

Example 5 Testing of Post-Emergent Herbicide Application on Transgenic Maize Containing AAD-1 and PAT

Transgenic Hi-II maize plants containing the AAD-1 and PAT expression cassette (RB7 MAR v3::Zea Maize Ubiquitin Promoter v2::AAD-1 v3::Zea Maize Per5 3′UTR v2::Rice Actin1 Promoter v2::PAT v3::Zea Maize Lipase 3′UTR v1) from pDAB3404 and Hi-II non-transgenic control plants were propagated for testing. Seed were planted into Metro Mix Media (Sun Gro Horticulture Inc., Bellevue, Wash.) and subirrigated with Hoagland's solution until wet, then allowed to gravity drain. Pots were placed in a glasshouse environment set to 27° C. until the germinated plants reached the V1-V3 growth stage. At or about, the V1-V3 growth stage, the maize plants were spayed using a track sprayer and a drop down nozzle calibrated to deliver a187 L/ha solution of herbicide at the 1× Field Rate (Table 7). After treatment the plants were placed in the greenhouse and scored via visual injury assessment after 14 days. Table 7 also lists the tolerance of the plants to the applied herbicides as determined by the visual injury assessment.
